DEVICE FOR PRODUCING ON TEXTILE FABRICS A SILKY LUSTER.

SPECIFICATION forming part of Letters Patent No. 755,469, dated March 22, 19014,

Application filed August 20, 1902. Serial No. 120,361. (No model.)

To a whom it may concern.-

Be it known that I, J OSEPH EcK, manufacturer, a subject of the King of Prussia, German Emperor, residing at Dusseldorf, in the Kingdom ofPrussia,German Empire, have invented a new and Improved Device for Producing on Textile Fabrics a Silky Luster, of which the following is a specification.

There exist already pressing-rollers or pressingplates by means of which a silky luster may be produced on textile fabrics, said roller or plate being provided for that purpose with fine net-like engravings consisting of small meshes formed by embossed or incised portions adapted to reflect the rays falling upon a textile fabric treated with such a roller or plate. This is effected by pressing the engraved roller or plate upon the fabric, so as thereby to cause the small meshes or embossed or incised portions to be impressed into or upon that fabric. The small surfaces of said portions representing the meshes of the netlike engraving reflect the rays wherever such fall upon said surfaces, the effect thus produced being the appearance of a silky luster upon the fabric. If the surfaces of the embossed or incised meshes are equally sloping, a part of the rays falling upon the pressed fabric gets lost in the V-shaped cavities of the incised meshes or in the V-shaped flutes between the embossed meshes, and is thus of no use for the production of the silky luster.

The object of my invention is torender also these rays useful. To attain this object, the portions representing the meshes are so formed upon the roller or plate that they have slopes of different inclinationsthat is to say, short and steep surfaces alternate with long ones of less inclination, so that also those rays are rendered useful which fall deeper into said cavities or flutes.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the several views, and in which- Figure 1 is a side view of a pressing-roller, the surface a of which has an engraving formed according to my invention, which, however, cannot be represented because of its minuteness. Thesrnall meshes of this net may have the shape of triangles, quadrangles, rhombs, parallelograms, circles, ellipses, polygons, and the like, and each of the small surfaces belonging to a mesh is sloping, the degree of inclination being in no case uniform. Fig. 2 shows, on a greatly-enlarged scale, parts of the surface of such roller, (or plate,) the meshes forming in this instance parallelograms. Fig. 3 is a section in line E F of Fig. 2. Fig. 4: is a view similar to Fig. 2, the parallelogramsbeing incised instead of embossed, as in Fig. 2. Fig. 5 is a section in line G H of Fig. 4:. Fig. 6 is a diagrammatical representation of a few quadrangular pyramids drawn on a greatlyincreased scale and intended to convey a better idea of the gist of the invention.

The embossed parts 6, Figs. 2and 3, formed either upon the rolleraor upon a plat-e having the same area of surface as that roller, consist practically each of a pyramidal or pyramid-like body, and when incised parts are used-such, for instance, as 7, Figs. 4 and 5the cavities which they form or by which they are formed are, so to say, negatives of said parts 6. The base of the positive parts 6 or of the negative parts 7 may be quadrangular or not,but the summit when formed by a point is not situated above the middle of the base, and

when formed by a line is also not situated above the middle of the base; but its position is always such that the inclined surfaces of generally triangular shape have different inclinations. There are, in fact, short and steep surfaces and long ones of less inclination, and

they alternate with each other, as shown. There are two sets of parallel rows of the embossed or incised parts or positions; but the 1 rows of one set and those of the other do not form rectangles with each other. For instance, in the case of four-sided pyramids, as in the example shown, two opposite angles are acute, and the other two are obtuse, so that consequently one set of rows is inclined with respect to the other. To make this clearer,

I refer particularly to Fig. 6, which shows four of such meshes, as 6, Fig. 2, eachihaving a quadrangular base of rhombic shape and a pyramid b 0 d o, the triangular sides of which are not only of diiferent size or area, but partly of different inclination, too, the summit, however, being located, so to say, inside, although, of course, above the area of the base. These pyramids are formed by two systems of grooves cut or otherwise worked into the respective ground-plate and crossing each other at an angle of less or more than ninety degreesfor instance and in fact, preferably of from thirty to sixty degrees or one hundred and twenty to'one hundred and fifty degrees, as the case may be. The grooves of the one series may have such a section as indicated by m n 0, and those of the other series may have such a section as indicated by age. When cutting these latter grooves into the plate, the sides of the grooves of the first series are turned into triangles 5 and 0, and the grooves of the second series produce at the same time the triangles d and *0. Thus the triangles I) are the remaining portions of the inclined surfaces m m n n, the triangles 0 are the remaining portions of the inclined surfaces 7 0 0 n n, the triangles d are the immediatelyformed portions of the inclined surfaces 2 z 3/ 3 and the triangles o are the immediately-formed portions of the inclined surfaces 00 w y y, so that in this way the four sides I) 0 d 'v of each pyramid are formed- It does not form a part of my invention by which means or tools or by which method or process the grooves are formed, and it is, in fact, also immaterial whether there are positive four sided or three sided or five sided pyramids or similar bodies extending above the base or negative ones extending into base and forming cavitiesfor instance, such as 1-, Fig. 4the sides of which are as different in size and inclination as those of the positive bodies. The effect with respect to the production of the silky luster is in both cases the same.

I am aware of the previously-known methods described in the British specifications N 0. 4,593 of 1885, No. 7,637 of 1895, and No. 13,729 of 1899, and do not lay a claim to anything described in said prior publications; but

What I do claim, and desire to be granted as a patent of the United States, is

1. As a device for producing a silky luster upon textile fabrics, a pressing-tool having dle of the base, substantially as described.

3. As a device for producing a silky luster upon textile fabrics, a pressing-tool having upon its working surfaces rows of bodies having each an angular base and triangular sides, the latter having at least two different inclinations, the common point of meeting of all said sides being located outside aline extending perpendicularly through the middle of the base, substantially as described.

4:. As a device for producing a silky luster upon textile fabrics, a pressing-tool having upon and as its working surface rows of bodies having each a quadrangular base and triangular sides, the latter having each at least three different inclinations, substantially as described.

5. As a device for producing a silky luster upon textile fabrics, a pressing-tool'having upon or as its working surface rows of bodies having each an angular base and triangular sides, the latter having different inclinations, and said rows crossing each other at angles other than right angles, substantially as described.

6. As a device for producing a silky luster upon textile fabrics, a pressing-tool having upon and as its working surface rows of bodies having each a rhombic base and triangular sides, the latter beingall of different area, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
